Cloud Computing
Prof. Erwin M. Globio, MSITResource Speaker
PROF. ERWIN M. GLOBIO, MSIT
What is Cloud Computing?
• “A style of computing where scalable and elastic IT-related capabilities are provided ‘as a service’ to customers using Internet Technologies” .
PROF. ERWIN M. GLOBIO, MSIT
The Needs
• Users needs Application Software (such as office applications)
• Business needs Infrastructure (Software for enterprise business operation and Hardware for network and storage)
• Developers needs Platform (such as ROR working on a server environment)
PROF. ERWIN M. GLOBIO, MSIT
Software, Platform, and Infrastructure in companies
PROF. ERWIN M. GLOBIO, MSIT
Current Set-Up
• Users installs the software in the PC.(Cost of buying licensed software)
• Business invest hardware, software and infrastructure to automate their business process and store transactional data. (Capital Expenditure on server farm, storage and firewall)
• Application Developer Companies invests on platform for application development.
PROF. ERWIN M. GLOBIO, MSIT
Disadvantage of the Current Set Up
• Cost of Acquisition• Cost of Installation, Set up and training• Cost of Maintenance• Cost of Scaling Hardware• Cost of Disposal
PROF. ERWIN M. GLOBIO, MSIT
The Green Solution
• Cloud Computing both answers the computing needs of the users, business, and developers and counteracts the disadvantages of the current set up.
• It is where software applications, data storage, and processing capacity are accessed over the internet.
PROF. ERWIN M. GLOBIO, MSIT
Software, Platform, and Infrastructure placed in the Cloud
PROF. ERWIN M. GLOBIO, MSIT
PROF. ERWIN M. GLOBIO, MSIT
Cloud Computing Explained
• Allow users to run applications and store data online.
• Each offers a different level of user flexibility and control
PROF. ERWIN M. GLOBIO, MSIT
SAAS – Software As A Service
• Allow users to run online applications
PROF. ERWIN M. GLOBIO, MSIT
PAAS – Platform As A Service
• Allows users to create their own cloud applications using supplier – specific tools and languages
PROF. ERWIN M. GLOBIO, MSIT
IAAS – Infrastructure As A Service
• Allows users to run any applications as they please on cloud hardware of their own choice
PROF. ERWIN M. GLOBIO, MSIT
Three ways to cloud compute
• SAAS – Software As A Service• IAAS – Infrastructure As A Service• PAAS – Platform As A Service
PROF. ERWIN M. GLOBIO, MSIT
Software As A Service
• Is the easiest way to cloud compute• Where off-the shelf applications are accessed
over the Internet
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS - Microsoft Office Web Apps
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – Microsoft Office Web Apps
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – Image Editor
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – Video Editing
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – Creative Suite
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – Employee Information Management
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – Business Process Suite
PROF. ERWIN M. GLOBIO, MSIT
Example of SAAS – CRM Solution
PROF. ERWIN M. GLOBIO, MSIT
SAAS Pros and Cons
• Free or via paid subscription• Accessible to any computer or internet
enabled mobile device• Facilitates collaborative working• Generic applications not always suitable for
business use
PROF. ERWIN M. GLOBIO, MSIT
PAAS – Platform As A Service
• Provides environment and tools for creating for creating new online applications
PROF. ERWIN M. GLOBIO, MSIT
Example of PAAS
PROF. ERWIN M. GLOBIO, MSIT

Example of PAAS
PROF. ERWIN M. GLOBIO, MSIT
PAAS Pros and Cons
• Rapid development at low cost• Private or Public Deployment• Limits developers to provider languages and
tools• Risk of Vendor Lock - in
PROF. ERWIN M. GLOBIO, MSIT
Advantage of Cloud Computing
• Economies of Scale – underutilization and misappropriated hardware become a thing of the past. The cloud enables compute, storage and RAM resources to be more efficiently managed, provisioned and scaled, all within a shared environment.
PROF. ERWIN M. GLOBIO, MSIT
Advantage of Cloud Computing
• Cost Control – knowing exactly what you are using and how much that usage will cost you allows for a much stricter control over expenditures.
• “Disposable IT” – companies have the ability to create, use and destroy infrastructure based on their business needs.
PROF. ERWIN M. GLOBIO, MSIT
Advantage of Cloud Computing
• Burstable Workloads– scaling based on demand allows organizations to efficiently use infrastructure in a timely basis.
• Avoiding Capital Expenditure – with cloud computing, infrastructure becomes an operating expense with no need to amortize hardware costs over time.
PROF. ERWIN M. GLOBIO, MSIT
Types of Cloud Deployment Infrastructure
• Private (single tenant environment)– Hosted and on premises(in house)
• Public (shared environment)• Hybrid (combination)
PROF. ERWIN M. GLOBIO, MSIT
In Summary how will you know if it is cloud computing
• If its offered as a Service whether software, Infrastructure or Platform its cloud computing. Think of it as if you are renting the use of the software, infrastructure and platform. e.g. Google Docs, pixelator, GoGrid.com,prezi,
NetSuite, Amazon's Elastic Compute Cloud (AWS), but IBM, VMware,HP, Salesforce.com’s Force.com, Google’s App Engine, andMicrosoft’s Azure
